Contextualism

This article is about epistemological and ethical contextualism. For information about semantic contextualism, see Context principle.

Contextualism describes a collection of views in philosophy which emphasize the context in which an action, utterance, or expression occurs, and argues that, in some important respect, the action, utterance, or expression can only be understood relative to that context.[1] Contextualist views hold that philosophically controversial concepts, such as "meaning P", "knowing that P", "having a reason to A", and possibly even "being true" or "being right" only have meaning relative to a specified context. Some philosophers[2] hold that context-dependence may lead to relativism;[3] nevertheless, contextualist views are increasingly popular within philosophy.[1]

In epistemology, contextualism is the treatment of the word 'knows' as context-sensitive. Context-sensitive expressions are ones that "express different propositions relative to different contexts of use".[6] For example, some terms that are relatively uncontroversially considered context-sensitive are indexicals, such 'I', 'here', and 'now'. While the word 'I' has a constant linguistic meaning in all contexts of use, whom it refers to varies with context. Similarly, epistemic contextualists argue that the word 'knows' is context sensitive, expressing different relations in some different contexts.

Contextualism was introduced, in part, in order to undermine skeptical arguments that have this basic structure:

I don't know that I am not in an skeptical scenario H (e.g., I'm not a brain in a vat)

If I don't know that H is not the case, then I don't know an ordinary proposition O (e.g., I have hands)

Conclusion: Therefore, I don't know O

Contextualist solution is not to deny any premise, nor to say that the argument does not follow, but link the truth value of (3) to the context, and say that we can refuse (3) in context—like everyday conversational context—where we have different requirements to say we know.

The main tenet of contextualist epistemology, no matter what account of knowledge it is wedded to, is that knowledge attributions are context-sensitive. Then the truth values of out term "know" depend on the context in which it is used . We can realize that in the context in which the standards to claim truthfully knowledge are so high—e. e., in skeptical context—if we said something like 'I know that I have hands' then this statement would be false. Nevertheless, if we utter the same proposition in an ordinary context—e.g., in a cafe with friends--, where lower standards are in place , the statement would be truth, even more, it's negation would be false. So, only when we participate in philosophical discourses of the skeptical sort, do we seem to lose our knowledge. However, once we leave the skeptical context, we can truthfully say we have knowledge.

That is, when we attribute knowledge to someone, the context in which we use the term 'knowledge' determines the standards relative to which "knowledge" is being attributed (or denied). If we use it in everyday conversational contexts, the contextualist maintains, most of our claims to "know" things are true, despite skeptic's attempts to show we know little or nothing. But if the term 'knowledge' is used when skeptical hypotheses are being discussed, we count as "knowing" very little, if anything. Contextualists use this to explain why skeptical arguments can be persuasive, while at the same time protecting the correctness of our ordinary claims to "know" things. It is important to note that this theory does not allow that someone can have knowledge at one moment and not the other, for this would hardly be a satisfying epistemological answer. What contextualism entails is that in one context an utterance of a knowledge attribution can be true, and in a context with higher standards for knowledge, the same statement can be false. This happens in the same way that 'I' can correctly be used (by different people) to refer to different people at the same time.

What varies with context is how well-positioned a subject must be with respect to a proposition to count as "knowing" it. Contextualism in epistemology then is a semantic thesis about how 'knows' works in English, not a theory of what knowledge, justification, or strength of epistemic position consists in.[7] However, epistemologists combine contextualism with views about what knowledge is to address epistemological puzzles and issues, such as skepticism, the Gettier problem, and the Lottery paradox.

Contextualist accounts of knowledge became increasingly popular toward the end of the 20th century, particularly as responses to the problem of skepticism. Contemporary contextualists include Michael Blome-Tillmann, Michael Williams, Stewart Cohen, Keith DeRose, David Lewis, Gail Stine, and George Mattey.

Thus, the standards for attributing knowledge to someone, the contexualist claims, vary from one user's context to the next. Thus, if I say "John knows that his car is in front of him", the utterance is true if and only if (1) John believes that his car is in front of him, (2) the car is in fact in front of him, and (3) John meets the epistemic standards that my (the speaker's) context selects. This is a loose contextualist account of knowledge, and there are many significantly different theories of knowledge that can fit this contextualist template and thereby come in a contextualist form.

For instance, an evidentialist account of knowledge can be an instance of contextualism if it's held that strength of justification is a contextually varying matter. And one who accepts a relevant alternative's account of knowledge can be a contextualist by holding that what range of alternatives are relevant is sensitive to conversational context. DeRose adopts a type of modal or "safety" (as it has since come to be known) account on which knowledge is a matter of one's belief as to whether or not p is the case matching the fact of the matter, not only in the actual world, but also in the sufficiently close possible worlds: Knowledge amounts to there being no "nearby" worlds in which one goes wrong with respect to p. But how close is sufficiently close? It's here that DeRose takes the modal account of knowledge in a contextualist direction, for the range of "epistemically relevant worlds" is what varies with context: In high standards contexts one's belief must match the fact of the matter through a much wider range of worlds than is relevant to low standards contexts.

It is claimed that Neurophilosophy has the goal of contextualizing. "We must contextualize questions usually dealt with in the physical and epistemological domains into the context of the empirical domain, the domain of observation in third-person perspective." "Rather than approaching the metaphysical and epistemological issues [about the nature and features of brain and mind] from a mind-based (as in traditional philosophy) or brain-reductive (as in neuroscience) perspective, we therefore pursue a brain-based strategy and thus a non-reductive neurophilosophy." "The various arguments against the material or physicalistic view of consciousness...are directly compared with the empirical data and are thus put into the empirical, that is, neuroscientific context of consciousness."[8]

However, contextualist epistemology has been criticized by several philosophers. Contextualism is opposed to any general form of Invariantism, which claims that knowledge is not context-sensitive (i.e. it is invariant). More recent criticism has been in the form of rival theories, including Subject-Sensitive Invariantism (SSI), mainly due to the work of John Hawthorne (2004), and Interest-Relative Invariantism (IRI), due to Jason Stanley (2005). SSI claims that it is the context of the subject of the knowledge attribution that determines the epistemic standards, whereas Contextualism maintains it is the attributor. IRI, on the other hand, argues that it is the context of the practical interests of the subject of the knowledge attribution that determines the epistemic standards. Stanley writes that bare IRI is "simply the claim that whether or not someone knows that p may be determined in part by practical facts about the subject's environment."[9] ("Contextualism" is a misnomer for either form of Invariantism, since "Contextualism" among epistemologists is considered to be restricted to a claim about the context-sensitivity of knowledge attributions (or the word "knows"). Thus, any view which maintains that something other than knowledge attributions are context-sensitive is not, strictly speaking, a form of Contextualism.) DeRose (2009) responds to recent attacks on contextualism, and argues that contextualism is superior to these recent rivals.

An alternative to contextualism called contrastivism has been proposed by Jonathan Schaffer. Contrastivism, like contextualism, uses semantic approaches to tackle the problem of skepticism.[10]

Recent work in the new field of experimental philosophy has taken an empirical approach to testing the claims of contextualism and related views. This research has proceeded by conducting experiments in which ordinary non-philosophers are presented with vignettes which involve a knowledge ascription. Participants are then asked to report on the status of that knowledge ascription. The studies address contextualism by varying the context of the knowledge ascription, e.g., how important it is that the agent in the vignette has accurate knowledge.

In the studies completed up to this point, no support for contextualism has been found.[11] This critique of contextualism can be summed up as: stakes have no impact on evidence. More specifically, non-philosophical intuitions about knowledge attributions are not affected by the importance to the potential knower of the accuracy of that knowledge. Some may argue that these empirical studies for the most part have not been well designed for testing contextualism, which claims that the context of the attributor of "knowledge" affects the epistemic standards that govern their claims. Because most of the empirical studies don't vary the stakes for the attributor, but for the subject being described, these studies are more relevant to the evaluation of John Hawthorne's "Subject-Sensitive Invariantism" or Jason Stanley's "Interest-Relative Invariantism"—views on which the stakes for the putative subject of knowledge can affect whether that subject knows—than they are of contextualism. However, Feltz & Zarpentine (forthcoming) have tested the stakes for both the subject and the attributor, and the results are not in keeping with contextualism. Experimental work continues to be done on this topic.[12]
